Satellite infrared image of the US-Canada border, showing Montana, southwestern Saskatchewan and southeastern Alberta, Canada. This area is cattle grazing territory for the Canadian provinces, but is wheat growing land for the US side of the border (where cattle is grazed further south). The Milk River cuts across the image diagonally, and a small outlier of the Rockies stands out in red (vegetation) in this northernmost part of the Great Plains.
